I’ve been doing this for years now, so I’ve pretty much figured things out and it looks pretty straightforward in the video. Still, back when I was getting set up, I remember spending hours and hours at it. Even today, just one wrong number and the whole process falls apart (and three failures in a row and the account shuts down, making you go to the bank to get it working again). In fact, the reason I thought to prepare this recording is that in my first time through I got all the way to the last step and did something wrong, which made me start over and think to record my second try.
I should also point out that this is ONLY possible in Internet Explorer. Ecommerce stuff doesnt work in Korea under any other browser… by government order! (Fortunately, this rule was relaxed recently but the number of Korean sites which are now browser independent still approaches zero.)
